HDPE PIPES – TELECOM DUCTS
FOR LST NETWORKS AND TELECOM
DESCRIPTION
The high-density polyethylene pipes are delivered in coils of 100 to 1000 meters. They are black. The resins used forthe manufacture of the IP range to the cladding are obtained by polyethylene HD granules polymerization.
AVANTAGES
The PE sheaths present:
- Very smooth walls associated with a low coefficient of friction loss, allowing a large print facility cableswithout any damage over long lengths
- A great flexibility
- High resistance to soil aggression such as acids, bases and salts
- Networks durability with exceptional impact resistance
- Excellent dielectric properties
- A very good UV resistance.
APPLICATION AREAS
The technique of cable sheathing by PEHD pipes is applied to areas that concern the protection of buried cables for particular :
• To telephone networks
• Transport electrical energy from low voltage.
INSPECTION AND TESTING LABORATORY
- Dimensional controls (nominal thickness, outer diameter min, max, average outside diameter, length crowns).
- Pressure test
- Tensile tests / elongation.
- Determination of hot longitudinal shrinkage
- These checks and tests are carried out according to well-defined frequencies.

MARKING
The SOTICI PE ducts are marked to ensure complete traceability of our products. In addition to the date and time of production and then the production line, we can go back to the raw material which was used to produce the tube in question. A metric marking is applied to the crowns. this marking facilitates the daily work of all users by informing them on the remaining length of the crowns to enable them to better manage their stocks and quantities consumed. The elements that make up this mark:
For specific projects, this marking may be adapted according to customer demand. Contact us for transmit and study the feasibility of your request.
